CVE-2023-53641: Software Security Vulnerability Vulnerability
MODERATECVE-2023-53641 is a MODERATE (CVSS 5.5) security vulnerability vulnerability (CWE-401: Missing Release of Memory after Effective Lifetime) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.. Remediation is available in the latest vendor maintenance releases.
CVE-2023-53641 at a Glance
Security Impact
CVSS: 5.5
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).
How to Fix CVE-2023-53641
To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:treeHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2023-53641, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:treeAnalyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.
Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-401: Missing Release of Memory after Effective Lifetime, where the product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse. In Software, software state validation or input boundaries are circumvented during processing.

"details" : "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath9k: hif_usb: fix memory leak of remain_skbs\n\nhif_dev->remain_skb is allocated and used exclusively in\nath9k_hif_usb_rx_stream(). It is implied that an allocated remain_skb is\nprocessed and subsequently freed (in error paths) only during the next\ncall of ath9k_hif_usb_rx_stream().\n\nSo, if the urbs are deallocated between those two calls due to the device\ndeinitialization or suspend, it is possible that ath9k_hif_usb_rx_stream()\nis not called next time and the allocated remain_skb is leaked. Our local\nSyzkaller instance was able to trigger that.\n\nremain_skb makes sense when receiving two consecutive urbs which are\nlogically linked together, i.e. a specific data field from the first skb\nindicates a cached skb to be allocated, memcpy'd with some data and\nsubsequently processed in the next call to ath9k_hif_usb_rx_stream(). Urbs\ndeallocation supposedly makes that link irrelevant so we need to free the\ncached skb in those cases.\n\nFix the leak by introducing a function to explicitly free remain_skb (if\nit is not NULL) when the rx urbs have been deallocated. remain_skb is NULL\nwhen it has not been allocated at all (hif_dev struct is kzalloced) or\nwhen it has been processed in next call to ath9k_hif_usb_rx_stream().\n\nFound by Linux Verification Center (linuxtesting.org) with Syzkaller.",
